SlicePurchaseActivity don't send canceled on manual finish

onDestroy is called when the user closes the app or when finish() is
called programatically. We call finish after sending a response from the
slice purchase activity, but we shouldn't send the canceled response
because the user didn't close the application. Add a check to see
whether onDestroy was called programatically or due to user action.
